AIGO EROS Q / AIGO EROS K / IRULU Surfans F20 / AGPTek H3 / HIFI WALKER H2

[Tarik]

i guess theres still tons for you to do still in porting rockbox to these players. Any micro updates would be received with love but otherwise I patiently and keenly wait

Yesterday I committed support in the RockboxUtility (no binary builds available as of this writing), complete with patches for the stock firmware images.

A few minutes ago I finished uploading updated bootloader images with some critical fixes for the hotswap and external USB storage support.

It's coming along nicely.

Hi, I just registered to ask you this. Does that mean that there's full Rockbox support for this device?

Yep.

I bought a surfans F20 on eBay for 70 bucks with some gnarly cosmetic issues but supposedly fully functional.    Will the Bluetooth work in Rockbox?   If i could grab any info for it like looking up the bt chip part number id be glad to if getting it apart isnt a total bitch.

Rockbox doesn't have any bluetooth functionality on any device yet - I understand it's been a "someday" project for a while. I had mine apart as well and there was a metal shield around the bluetooth module that I wasn't able to get off, so if you could manage to do that it would probably help a lot.

I have the pictures I took linked somewhere earlier in this thread if you want to take a look at how it comes apart, assuming the Surfans is anything like the Hifi Walker version. I just kind of pried my way in, but I think the way to do it without damage would be to take the screen protector off and there should be 2 screws under there that hold the back on, then the back cover should just pop out with a little effort. Just be a little careful, as the bluetooth antenna and battery are both attached to the back.

To elaborate a little, what's missing for Bluetooth on the hosted port is a UI and all the 'glue' code to actually push out audio. It might be quite a bit of work but assuming it all goes through normal Linux/ALSA/BlueZ APIs, it shouldn't be too difficult to implement.

The native port is a different story - we'd need a Bluetooth stack, which probably means porting BlueZ, and drivers for the BT hardware, most likely by porting Linux drivers, in addition to all that front-end UI and glue code. IMHO that's probably not worth the effort - it would be easier and more useful to port a mainline Linux kernel and build our own userspace to run Rockbox.

[fennectech]

This hosted one.  I love the idea.  Is there any chance we could get a terminal to the underlying linux environment too?   It has usb host. So perhaps even a keyboard?  Also.  Can you link me to the hosted port of rockbox?

Installation instructions are on the wiki here: https://www.rockbox.org/wiki/AIGOErosQK. You probably want the pre-patched updates, which work like a normal original firmware update. Once you've installed that you can extract a daily build of Rockbox to the SD card.

As for a terminal, you can get a serial console using the 'run script' option in the Rockbox bootloader, once you've installed Rockbox. I don't have one of these players but I have used this script on the FiiO M3K, which runs basically the same Linux environment:

Code: [Select]

#!/bin/ash
insmod /lib/modules/3.10.14/kernel/driver/staging/dwc2/dwc2.ko
insmod /lib/modules/3.10.14/kernel/driver/usb/gadget/libcomposite.ko
insmod /lib/modules/3.10.14/kernel/driver/usb/gadget/u_serial.ko
insmod /lib/modules/3.10.14/kernel/driver/usb/gadget/usb_f_serial.ko
insmod /lib/modules/3.10.14/kernel/driver/usb/gadget/usb_f_acm.ko
insmod /lib/modules/3.10.14/kernel/driver/usb/gadget/g_serial.ko
getty /dev/ttyGS0 115200
rmmod g_serial
rmmod usb_f_acm
rmmod usb_f_serial
rmmod u_serial
rmmod libcomposite
rmmod dwc2

That should give you a serial port running getty - assuming the script works - which you can connect to using any serial console app, eg. minicom.

EDIT: Bilgus has an old bluetooth menu patch on gerrit which might be a good starting point for the UI - g#3044.

Any chance i could get a built version?  i dont have a dev enviroment for rockbox here.   anyway im setting things up   also   will auto reconnect to bluetooth headphones ever be a thing on here?

Edit   set up a build enviroment and compilation fails :<

[amachronic]

There's no pre-built version since it's only a patch on gerrit. Not surprising it won't compile as-is, since it's pretty old and there's merge conflicts. I just thought it might be helpful in some way.

I may be getting an Aigo eros q soon.  On the aigo eros q/k target status page:

https://www.rockbox.org/wiki/AIGOErosQK

It says "The RockboxUtility fully supports these players (note that the current 1.4.1 release is from 2019 and will not work)"

Any idea which of the older (windows) version will work?  All the other versions are from 2014 and earlier, I'm guessing those wouldn't work with this newer player.

The manual installation instructions seem a bit difficult to me.

[dconrad]

None of the older windows Rockbox Utility versions will work, you need a version newer than 1.4.1. I thought that there was a development build for download somewhere, but I can't seem to find it. At the bottom of This page there is a link to where a current development build is supposed to be hosted, but it seems to be broken. Presumably there is a build somewhere around here.

If nobody has a download for Rockbox Utility which supports it, doing a manual installation isn't really all that hard. The firmware patching stuff isn't necessary, there are pre-patched firmware update files, so the process should be:

• Download the appropriate pre-patched update file for your player and rename it to update.upt. Place it into the root directory of the SD card
• Grab the latest daily build for the player and unzip it into the root directory of the SD card (should end up with a ".rockbox" folder on the root of the card)
• Go into the settings menu and select firmware update.
• Upon reboot, select rockbox from the initial menu

None. Why should an even older version work if said version is too old? You need something more recent than 1.4.1.

It's a sticky in the "Rockbox Utility" subforum: https://forums.rockbox.org/index.php/topic,53588.0.html

It does sound simple.  Thanks guys.  Anyways, the reason I say I "may" be getting one, is that I just ordered this for $29. Sounds too good to be true.:

Well, judging by the "out of stock" status, maybe there was only one somebody was trying to get rid of, and you got it 

Or somebody forgot a couple "1"s in the form to put up the posting haha

Watch out for 3rd party sellers on walmart.com, walmart will not do anything except take your money, seller sent you a used broken device? POUND SAND
